- reverse the order of the two lines - so you start with the keyword func declaring the function
- you don't need a backslash
- greeting shouldn't be inside the parentheses, the parentheses go after it like this: greeting()
- then you need a set of curly braces { }
- inside those curley braces is where you put the things that the function does: in this case printing out "Hello"
- there should be no space between println and the parentheses: println("Hello")
- make sure there are no extra spaces inside the parentheses or inside the quotes. Both the Swift language and this particular challenge are picky.
So the whole code would look like this:
func greeting() {
println("Hello")
}
